Car fuel oil meter

Abstract

The invention relates to a car fuel oil meter mainly comprising an oil tank 1, a filter 2, an oil-taking flow sensor 3, an engine fuel oil pump 4, an oil return high-frequency fluctuation pressure filter 5, an oil return flow sensor 6, a CPU controller 7 and a fuel oil consumption value display 8. By adopting an oil return high-frequency fluctuation pressure filter and returned oil-taking flow difference technology, the car fuel oil meter can rapidly and accurately meter the fuel oil consumption (oil consumption) of cars taking diesel, gasoline, ethanol and the like as fuel in the driving process and can display instant oil consumption, daily oil consumption, monthly oil consumption and yearly oil consumption, thereby being beneficial to the saving of energy and the reducing of emission of the cars, improving the driving technique of a driver, precisely metering the oil consumption of a car driven by a driver working in shifts and effectively managing the oil consumption of a motorcade of a motor corporation.

Description

technical field [0001] The invention relates to an automobile fuel meter, which is used to quickly and accurately measure the fuel consumption (fuel consumption) of a vehicle fueled by diesel, gasoline, ethanol, etc. during driving, and can display instantaneous fuel consumption, current day fuel consumption, current month fuel consumption and current year fuel consumption. It is helpful for energy saving and emission reduction of automobiles, for drivers to improve their driving skills, for drivers of shift vehicles to accurately count their own fuel consumption, and for automobile companies to effectively manage their fleet's fuel consumption, which belongs to the field of transportation tools. Background technique [0002] For cars, the accurate measurement of fuel consumption is very important: when two taxi drivers drive a taxi, they must know the exact fuel consumption of the previous shift before they take over the shift; It is also necessary to know the accurate fue...

AI Technical Summary

Problems solved by technology

The utility model patent ZL200720091868.2 invented a fuel meter for automobile engines, which uses the flow difference between the fuel inlet meter and the oil return meter to calculate the actual fuel consumption. high

The utility model patent ZL01249839.4 invented an automotive electronic numerical control fuel meter, which uses the sliding resistance of the float in the fuel tank to measure the actual fuel consumption. The disadvantage is that the fluctuation of the liquid level and the angle of the vehicle will affect the result, and the accuracy is not high.

The most commonly used fuel metering method is still based on the reading of the fuel dispenser flow meter when the vehicle is refueled. The disadvantage is that it cannot display the instantaneous fuel consumption of the vehicle.

There is also a lack of a fast and accurate method of fuel metering for vehicles
